New cycle path not routing

I added a way joining an existing cycle path and a road.

This is the way that I added: http://www.openstreetmap.org/browse/way/158514786

It shows that its end nodes are also parts of other ways, and it has also got the "bicycle=designated" attribute on.

Yet when I go on www.openrouteservice.org and try to do a bicycle route from say

Pos@: -0.769655 53.227528

to

Pos@: -0.802614 53.222493

by bicycle, then it doesn't route using my new way. It should not go all the way east to Harby!

i.e., should probably be significantly less than 10km, not 18.9km.

Can anyone please let me know what I have failed to do or done wrong?

Thank you
